ITIS lumps all neopteran orders together in this infraclass without subdivision; other authorities recognise several superorders within it. Almost universally accepted are the Exopterygota - hemimetabolous neopterans, in which the wings are already visible before the adult stage and no pupa or chrysalis stage occurs -, and the Endopterygota, the holometabolous insects in which the wings develop inside the body during the larval stage and only become external appendages during the pupa or chrysalis stage.
